COLLADA is a COLLAborative Design Activity for establishing an open standard digital asset schema for interactive 3D applications. It involves designers, developers, and interested parties from within Sony Computer Entertainment America (SCEA) as well as key third-party companies in the 3-D industry. With its 1.4.0 release, COLLADA became a standard of The Khronos Group Inc., where consortium members continue to promote COLLADA to be the centerpiece of digital-asset toolchains used by the 3-D interactive industry.
COLLADA™ defines an XML-based schema to make it easy to transport 3D assets between applications - enabling diverse 3D authoring and content processing tools to be combined into a production pipeline. The intermediate language provides comprehensive encoding of visual scenes including: geometry, shaders and effects, physics, animation, kinematics, and even multiple version representations of the same asset.COLLADA FX enables leading 3D authoring tools to work effectively together to create shader and effects applications and assets to be authored and packaged using OpenGL® Shading Language, Cg, CgFX, and DirectX® FX.
glTF - runtime asset format for WebGL, OpenGL ES, and OpenGL
The "glTF" project aims to define a final stage OpenGL Transmission Format to enable rapid delivery and loading of 3D content by WebGL, OpenGL, and OpenGL ES APIs. glTF together with COLLADA comprise a standards-based content pipeline for rich 3D web and mobile applications. glTF Specification is a work-in-progress from the COLLADA Working Group; it is not an official Khronos-ratified specification yet. It is incomplete and subject to change. The draft specification and related converters and loaders are available on github.
COLLADAMax and COLLADAMaya are new implementation of a 3ds Max or Maya plug-ins to export scene or parts of it to a COLLADA file, released under an MIT-license. In contrast to other existing COLLADA exporters, these new plug-ins do not store the COLLADA document in an intermediate data model but writes it directly to file. This leads to a dramatic reduction of memory consumption and to much better performance.
The COLLADA intermediate language specification is intended to standardize 3D data, but there’s a wide variation in the way applications work with COLLADA files. To help developers adhere to the standard and create 3D tools that work together seamlessly, the Khronos Group created the COLLADA Conformance Test Suite (CTS).
Information about products that provide COLLADA plug-ins or that import or export COLLADA. This information is submitted by various vendors and users. To assure that implementations of Khronos specifications meet a consistent standard of the highest quality, the Khronos Group maintains Adopter Programs that provide access to conformance tests for verification by Khronos that a product or implementation conforms to the specification. To find out how you can use the COLLADA trademark (in text or logo form) in association with your product please visit Khronos Adoption and Conformance Testing.
The COLLADA extensions directory is where vendors may follow the official COLLADA Extensions Process, to publish their extensions. These extensions are based on the COLLADA extensibility mechanisms that involve the use of the following elements: <extra>, <technique>, and <input>. Parametrization of effects is left out of this definition.
The COLLADA Document Object Model (DOM) is a C++ library for loading and saving COLLADA data. The latest official release of the DOM is version 2.2, which is available as a download on Sourceforge.
COLLADA Coherency Test
COLLADA Coherency Test is a command-line version of CoherencyTest from COLLADA Refinery. It checks whether a COLLADA dae file is coherent (properly composed). It is built using the COLLADA DOM library on Sourceforge. It is developed in C/C++ and built using MSVC.
Getting Started with COLLADA
A collection of articles containing COLLADA tutorials, annotated examples and user guides
CopperCube, the game engine focussing on WebGL has just been released in version 5. It now includes terrain support, video playback, network communication, iOS 8 WebGL support, shader programming, animation blending, and much more. There are also two new WebGL demos available on its website, showing it in action. A list of the new features with images is available as well. Read More
NVIDIA has co-sponsored the WebGL Widget contest by contributing a new Shield Gaming Tablet as one of the prizes. This is in addition to two WebGL books Toni Parisi by sponsored by O’Reilly media; and the WebGL book by Sumeet Arora sponsored by Packt Publishing. Submit your best WebGL Widget by November 25 for a chance to win! We've recently increased the size limit from 30K to 200K. What can you create? Read More
The COLLADA to glTF converter online tool allows you to convert your COLLADA models to glTF for use with Cesium. Simply drag-and-drop your COLLADA file (.dae) and any images it references by zipping them together. A self-contained glTF file will be downloaded once the conversion is finished, and a model preview will be shown below. Read More
